An Update on Chemical Origin of Life Friday, June 15, 2007

According to Science Daily, the study of the origin of life has made further progress.

A pair of scientists have proposed a model where natural selection is the seen as the driving force at chemical level. An enzyme catalyst might produce chemicals that other catalysts require, and they will seek that enzyme, and they stabilise and thus forming a complex. This process is coined as a “search, selection and memory” Darwinian process. For example:

The process could go like this: Catalyst A produces a chemical that catalyst B uses. Now, since B normally seeks out this chemical, sometimes B will be attracted to A — if its desired chemical is not otherwise available nearby. As a result, A and B will come into proximity, forming a complex.

Of course, currently this is only a proposed model. However, it is testable, and depends only on known chemical and physical laws (no skyhook required here).
